Location of the shim voxel. Preferably, the shim voxel should eb ~10% smaller, and the voxel boundaries should cross brain boundaries.
Shimming can be performed using the anatomical scan, or a single repetition GE-EPI volume. A B0 map should be acquired before performing the shimming.
Slice pacakges. The first slice should just be at the end of the olfactory bulb. The last slice should be at the start of the cerebelum.
The FOV saturation band (15 mm, not 4 mm as displayed below), should be located on the inferior boundaries of the slices.
